Question

Please give me the answer friends. ​

Answer 1

Step-by-step explanation:

Radius of semi circle = = 3.5 m

Length of rectangular field

= 20 – (3.5 + 3.5) = 20 – 7 = 13 m

Breadth of the rectangular field = 7 m

Area of rectangular field =

= 13 7 = 91

Area of two semi circles =

= = 38.5 m2

Area of garden = 91 + 38.5 = 129.5 m2

Now Perimeter of two semi circles = = 22 m

And Perimeter of garden

= 22 + 13 + 13

= 48 m
